s claims.l (Glisse-vs) l My inventionrelates to improvements in mixingmachines and has for an object thereof to provide a simple anddurableheavy duty device-of the present nature which will function in a highlyefficient manner to mix substances such paint and the like whilecontained in closed barrels or other relatively large receptacles.

Another object of the invention is to supply a heavy duty mixer having acradle equipped with clamping means for conveniently receiving barrelsand the like of various forms and rmly holding them in place within thecradle.

Afurther object of the invention is to provide means disposed beneathvthe cradle and having parts underslung therefrom for imparting arocking movement to 'said cradle.4

An additional feature of the invention resides in constructing thecradle from sheet material and in reinforcing the same by means ofbarrel 'checks and/or the cradle rocking means'.

.With the foregoing and other objects in view, which will appearin the'following description, the invention resides' in the novel combinationand arrangement of parts and inthedetails of construction hereinafterdescribed yand claimed.

vIn the drawings:

Fig. 1 is a' side elevational View of a mixer embodying my invention;Fig. 2 is a fragmentary planview thereof ;vv Fig. 3, is an `endelevational view of the same, portions .of the structure being brokenaway to reveal parts that otherwise would be concealed, and Fig. 4 is acentral sectional view taken on the line -l of Fig. 3.

Referring to the drawings, wherein similar parts are designated bysimilar reference characters throughout the several views, it will beobserved that the illustrated embodiment of my invention includes aframe consisting of a base I0 to which a pair of standards il aresecured. Supported upon said standards Ii and disposed between them is acradle indicated in its entirety b-y the reference'character A. Thiscradle A. is channel-like in form and preferably bent up from sheetmetal to provide a web I2 and upstanding side danges I3. Trunnions I4issuing from the side `flanges I3, are rockably mounted -in bearings i5on thestandards Il.- These trunnions are formed with attaching plates I6at their inner ends Aand said plates are secured to the sidey flanges I3ofthe cradle by means of bolts I'l.

Cradle rocking means are interposed between the base Iii and the web l2of the cradle A, said means being, in part, underslung from said web I2and, in part, mounted upon said base lil. Included in saidcradle-rocking means is' a plate I8 having spaced lever arms I9depending there- `from and braced with respect to said plate by meansVof reinforcing ribs 22. Thisplate i8 is substantially coextensive Withthe web' I2 and fis secured thereto by means of bolts 2I`. Cast iintegrally with the base 'IIl are two bearing posts 2 2 in the bearings23 of which a drive shaft 24 isv journaled. On this drive shaft 24 is aneccentric 2 5 and fitting this said eccentric 25 is a block 25 whichslides in the way 2!` formed between the'i .two lever arms I9.

A pan 28 rests on the base I il, each side of said pan occupying aposition between one of the bearing posts 22 and the. adjacent edges ofthe depending lever arms I9. This panZB Yfreely receives said lever armsI9 and is adapted to contain oil into which said arms dip, the splashofthe oil by said arms serving to `lubrlcate the Vbearing surfaces ofthe eccentric 25 andthe eccentric block 26 and the bea-ring surfacesofsaid eccentric block and the lever arms 19. The bearings: 23 on theposts 22 have bearing caps 23a". which admit of the application of thepower shaft 24 to said bearings 23 after the oil pan is placed vinposition between said bearing posts 22. Any suitable means may beVprovided for rotating the power shaft 24, it being my preference tomount a suitable power unit on the base lll and connect it with asprocket 29 or the like on `s aid power shaft.

Disposed within the cradle .A` and upon the web i2 thereof are a pair ofbarrel chocks 30. The

bases of `-these checks conform with and abut thel upper surface of theweb II2 and the ends of said surface rportions of the side flangesI I3of the cradle. Said checks are bolted to the web I2 by means of bolts3l, which preferably extend through the plate It of the driving meansand ychoc-irs conform with abut the adjacentv -The cradle A issuppliedwith side clamps B,"

one for each chock 32. Each side clamp includes a pair of rods 32, eachrod being pivoted toene of the cradle flanges i3 near the end of thecradle occupied by yoke to `bring it to bear uponthe upper .sideiof aits `respective chock. Slidably rrnormted at its ends on said rods is ayoke 3ft," said .rodsbeing threaded at their extremities and supzpliedwith hand nuts 35 cooperating with the 55 barrel and clamp the barreldown against said chock.

The cradle A is also supplied with end clamps C, each of which includesa pair of threaded studs 36, each stud issuing from the end of one ofthe cradle flanges I3. A clamp bar 37 is slidably mounted at its ends onthe studs 36 and hand nuts 38, threaded on said studs, cooperate withsaid clamp bar 3l to releasably clamp the same against its respectiveend of a barrel supported in the cradle A. At either side of said cradleA is a strap 39 which is bolted or otherwise suitably secured to itscorresponding cradle ange i3. Each strap 39 is preferably integral withthe opposed clamp studs 36 at the same side ofthe cradle and constitutesan eiective tie between said studs, whereby the side anges I3 of thecradle are relieved fromthe strains incident to the binding of the clampbars 3l against the Iends of a barrel.

In preparing the machine for the reception of a barrelcontainingmaterial to be mixed, the side clamps B are swung down into the positionshown in Fig; 4, wherein the rods 32 rest upon the hand nuts 38 of theend clamps C, said hand nuts 33, in such case, being retracted to permitthe corresponding retraction of the clamp bars Eil'. A barrel 40, suchas that indicated in dotted lines, is hoisted over the cradle A andlowered into position upon the chocks 3G. Thereafter, the side clamps Bare swung upwardly into the position, as shown in Fig. l and Fig. 3, andthe hand nuts 35 thereon are turned down to tighten the yoke 3d againstthe upper side of the barrel and thereby rigidly secure it inposition'upon the chocksiii.v Then, the hand nuts 38 of the end clamps Care tightened to bring the clamp bars 3l rmly against the ends ofthebarrel to preventy endwise movement of the barrel in the cradle A. Witha barrel iirmly secured within the cradle A, power is applied to theshaft 24 for rotating the same. As said shaft Irotates, the eccentric25, through the medium of the eccentric block 25, imparts alternatethrusts upon the lever arms l 9 ofthe cradle A, thusI causing saidcradle to be rocked back and forth. This oscillation of the barrelagitates the contents thereof and thoroughly mixes the same.

The iitting of the chocks 30 to the cradle A and the clamping thereof tothe web I?! of said cradle reinforces said web and so also does' theclamping of the plate i8 to said web. This reinforcement of the cradle Aby means of the chocks '30 and/or plate i8 permits' the use ofrelatively light material in the construction of said cradle.

The checks Bil are of wood or the like, while the yokes 34 and clampbars 3l are respectively supplied with liners 34a, 37a of similarmaterial. With said parts thus constructed, a barrel is 'nciselesslyheld within the container and is electrically insulated, this being animportant fealture especially in the event of the application tolthe-machine of metallic barrels whose contents are of an explosivecharacter.

The long leverage employed in the application of rocking forces to thecradle results in a highly efficient machine of quiet operation and longlife. Changes in the specific form of my invention,

` as herein disclosed, may be made within the 'scope of what is claimedwithout departing from the spirit of my invention.
